It would be cool to have an interstitial fluid version of something like this although. IF contains all sorts of stuff, like ketones, hormones, cortisol and more and is less invasive to measure than direct blood. It would be pretty awesome to have a generic biomonitor that monitored all of this. It would probably be amazing for athletes and scientific health studies.

"Interstitial fluid consists of a water solvent containing sugars, salts, fatty acids, amino acids, coenzymes, hormones, neurotransmitters, white blood cells and cell waste-products."
